Description

Description: This 4H9 monoclonal antibody reacts with human CD7 (also known as Leu-9 or gp40), a 40-kDa transmembrane glycoprotein belonging to the immunoglobulin superfamily. This molecule is expressed on peripheral blood T lymphocytes and natural killer cells, as well as on lymphoid and myeloid lineage precursors during adult hematopoiesis. Capable of providing a costimulatory signal and associating with CD3 and CD45, CD7 is involved in T cell activation. CD7 has also been detected on numerous T cell-derived leukemias and lymphomias. In fact, because CD7 expression is greater on CD4+ T cells in classical Hodgkin's lymphoma than in benign reactive lymph adenopathy, this molecule may be used as a diagnostic for Hodgkin's lymphoma. Blocking assays demonstrate that this clone recognizes the same epitope as clone 124-1D1. Applications Reported: This 4H9 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 4H9 antibody has been pre-titrated and tested by flow cytometric analysis on normal human peripheral blood cells. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser. Filtration: 0.2 μm post-manufacturing filtered.

CD7, also known as gp40 or Leu9, is a 40 kDa receptor and member of the immunoglobulin gene superfamily. It features an N-terminal region (amino acids 1-107) that is highly homologous to Ig kappa light chains, while its carboxyl-terminal region is proline-rich, forming a stalk from which the Ig domain projects. CD7 is prominently expressed on the majority of immature and mature T lymphocytes, as well as T cell leukemias. It is also found on natural killer cells, a small subpopulation of normal B cells, and malignant B cells. CD7 plays a crucial role in modulating immune cell activity. Cross-linking of surface CD7 enhances T cell and NK cell functions, as evidenced by increased calcium flux, expression of adhesion molecules, cytokine secretion, and proliferation. CD7 directly associates with phosphoinositol 3-kinase, and its ligation induces the production of D-3 phosphoinositides and tyrosine phosphorylation. The expression of CD7 is an important marker in leukemia diagnostics, highlighting its significance in both normal immune function and disease states.
